More than 85% of the bauxite mined globally is converted to alumina for the production of aluminium metal. An additional 10% goes to non-metal uses in various forms of specialty alumina, while the remainder is used for non-metallurgical bauxite applications. Non-metallurgical bauxite is used in: calcined products.
Jamaican bauxite was not used for the war effort. The techno logical problems arose because the North Americans were used to the largely trihydrate and coarse-grained North and South American bauxite and not the mixed hydrate and fine grained Jamaican bauxite. However, after the war, because of a number of fac
